摘要
识别电能质量扰动源是对电能质量进行研究的较高要求,目前开展的研究大多是针对谐波源的识别。与此同时,对闪变扰动源识别的研究却比较少。本文首先分析了闪变扰动源的闪变机理和闪变分量在电力系统中的传递规律。在此基础上,本文建立了负荷的暂态模型并提出了闪变扰动源识别算法。该算法可以快速有效地识别出供电系统中的闪变扰动源,从而可以找出闪变的责任者,进而为解决电压闪变问题提供有益的参考。最后本文用两个简单的算例验证了算法和模型的有效性。
To identify the power quality disturbance source is difficult for researcher of power quality. Now, the most research in this field is about identification of harmonic source. Meanwhile, the research of flicker disturbance source is few reported in literature. Firstly, the mechanism of flicker disturbance and transfer rule of flicker in power system are discussed in this paper. Then a suit of model and algorithms used to identify the flicker load are presented in this paper. These algorithms can identify the flicker disturbance source of power system fleetly and effectively, accordingly confirm the responsibility of voltage flicker. Lastly, two simple examples are used to prove the efficiency of these algorithms presented in this paper.
